Answer
A - gravitational pull
B - i don't know
C - The Sun exerts exactly the same amount of force that the Earth exerts on the Sun. This is summed in the equation
F=GM1M2r2
this is the equation that calculates the force between two objects based on their mass, the distance between them, and the gravitational constant.
The fact that the two forces are equal are also clearly stated in Newton’s Third Law of Motion, that “For every action, there is an equal and opposite re-action”. Forces always come in pairs, equal and in opposite directions.
